MOUNT PLEASANT, MI — The former Central Michigan University student who poisoned her roommate's iced tea with bleach will spend four months each in jail and under house arrest, according to a media report.

Isabella County Trial Judge Mark Duthie sentenced Bonkowski, 19, to eight months in jail and three years probation, the newspaper reported. Bonkowski, who is 18 weeks pregnant, will serve the last four months under house arrest, the Morning Sun reported.

Duthie sentenced Bonkowski under the Holmes Youthful Trainee Act, which seals her record immediately. If Bonkowski successfully completes her probation, the record will remain sealed and the charge would be dismissed.

The newspaper reported that Duthie also ordered Bonkowski to pay $915 in restitution to her former roommate for failing to continue paying her share of the rent at their off-campus apartment after the incident.

Prosecutors initially charged Bonkowski, 19, with the initial poisoning charge, which carries a maximum penalty of 15 years in prison. The attempt charge carries a five-year maximum penalty. She entered into the plea agreement last month.

When she pleaded, Bonkowski admitted to putting household cleaner into her roommate's drink while it was in the refrigerator Nov. 7 at their apartment in Union Township, the Morning Sun reported. She acknowledged that she knew doing so could cause injury, the newspaper reported.

Police have said that prior to the poisoning, Bonkowski and her roommate, who was 20 at the time, argued about dirty dishes. An affidavit signed by state police Trooper Joe Richards states that Bonkowski admitted to Trooper Douglas Hunt that she put bleach in the roommate's drink and did so "because (the roommate) is mean."

The roommate received medical treatment after drinking the tea, police said.

Bonkowski may serve her jail time in Macomb County, where she now lives, the Morning Sun reported.
